FOLDING CARTON.

Application filed December 27, 1911.

To all whom it may concern Be it known that I, FRANK KEILLER, a citizen of the United States, residing at the borough of Brooklyn, in the county of Kings, city and State of New York, have invented an Improvement in Folding Gartons, of which the following is a specification.

My invention relates to a box or cart-on for holding eggs in small quantities, and is so constructed that it may be knocked down to present a flat structure for convenience and economy of space in transportation or packing, and readily set up in form for receiving the eggs without disconnecting any of its members, or weakening its front wall by folding, and, at the same time, providing for ventilation of the box when filled.

In the accompanying drawing, in which like reference numerals indicate corresponding parts throughout the several views, Fig ure 1 illustrates a blank from which the earton is formed. Fig. 2 is a perspective view of one end of the blank partially folded, the remainder being broken off. Fig. 3 is a perspective view of the carton containing the filler and ready for use, and Fig. 4 is a perspective view showing the carton folded in form for packing or transportation.

The carton is preferably made from a single piece of suitable material, such as cardboard or thick paper, and is substantially rectangular in shape when set up for use.

The outline of the blank from which the carton is formed is shown in the plan view Fi 1.

T indicates the bottom of the box or carton.

2, 3, 4 and 5 indicate creases or fold lines around the same.

6 indicates the front wall of the box or carton, having creases or fold lines 7, 8, at either end thereof.

9 indicates a back wall, having creases or fold lines 10, 11, at either end.

12 indicates the lid of the box or carton, having a crease or fold line 13, which allows its outer extremity to be bent over to form a lip 14, adapted to be inserted between the inner surface of the front wall 6, and the end walls when the carton is set up for use. There is also a crease or fold line 15, at the junction of the lid 12 with the back wall 9.

16, 17, indicate end walls at opposite ends of the bottom 1.

1819 indicate end flaps at opposite ends Specification of Letters Patent.

of the front wall 6, and 2021 indicate end flaps at opposite ends of the back wall 9. The end flaps 18 and 19 are each provided with creases or fold lines 22 extending diagonally across their surface from the meeting points of the lines 45 with the line 2. The end walls 16, 17, have their sides slightly curved inwardly from their point of eonnection with the bottom 1, to their outer extremities. The end flaps 20-21 each have a cut-away portion, beginning at a predetermined distance from the meeting points of lines 10 and 11 with the line 15, and extending diagonally a certain distance and thence in a horizontal line to their outer extremities. These cut-away portions not only permit the blank to be set up without interference of the members, but also provide a ventilating opening 23 when the carton is set and in use. These end flaps 20, 21, are also provided with creases or fold lines 24. The end walls 16, 17, have no creases or fold lines.

In forming the carton from this blank, the front wall 6, and back wall 9, are turned upwardly at right angles to the bottom 1, along the lines 2 and 3, and the end walls 1617, are turned up in a similar manner along the fold lines 45, respectively. The end flaps 18, 19, and 20, 21, at the opposite ends of the front and back walls, are bent on the lines 78, and 1011, over against the outer surface of the end walls 16 and 17, respectively, when they are secured in such position by any suitable means, but preferably by wire staples 25, as shown, which pass through the end flaps and end walls when their ends are bent over toward each other and lie flat against the inner surface of the end walls. The lid 12 is then folded along the line 15, and the lip 14 turned downwardly along the line 13, when it is in shape to be inserted between the inner surface of the front wall 6, and the end walls 1617.

26 represents a cellular filler of the ordinary collapsible character for holding the eggs separated one from the other, and which is placed in the carton when it is set up and desired for use.

It will be seen that a carton constructed in this manner, may be readily collapsed into the flat form shown in Fig. 4, without disconnecting the end flaps from the end walls or disturbing the continuity of any of the members by simply pressing the ends in- Wardly until the inner surfaces of the end walls lie flat upon the bottom, as by so doing the respective end flaps will fold along the lines 22, 24, while at the same time, the front and back walls will fold along the lines 2, 3, the cartons being then in shape for packing in fiat form, one upon another, in any desired number, ready for transportation.

Then desired for use, such cartons may be quickly unfolded for receiving the filler 26 and the contents.

I claim as my invention:

A folding carton formed from a blank scored to provide a bottom, top, front, back, and end Walls all of which are without scores or creases, and end flaps at the ends of the front and back walls which overlap each other outside of the end Walls, said end flaps being scored in a manner to permit them to fold within the carton when the same is collapsed, said end walls having their sides curved inwardly from the point of connection with the bottom to their outer extremities, and said end flaps at the ends of the back Wall having a cut-away portion extending diagonally a certain distance and thence in a horizontal line to their outer eX- tremities, whereby when the carton is set up for use a ventilating opening is provided at each end of the same.

Signed by me this 21st day of December, 1911.

FRANK KEILLER.
